Wonder if the look a like(s) are to finish off the story for those characters. I don't know if Blake is leaving - this is just a total guess.

idk now the lookalike makes no sense to me. if she's already gone from the show, why bother with a lookalike? Unless Kristen leaves b/c the Eric thing gets found out, then Stefano hires this woman to take the fall to try to get her back but she won't? idk...spinning hay right now.
